Data Guard搭建完毕之后，执行开启归档路径2，结果发现不同步，
SQL> alter system set log_archive_dest_state_2=enable;
查看错误日志，发现有PING[ARC2]: Heartbeat failed to connect to standby ‘gqtzdb_dg‘. Error is 16047.的报错：
[oracle@KG-ORA-01 trace]$ tail -100f alert_gqtzdb.log
Mon Jul 03 18:19:10 2017
Using STANDBY_ARCHIVE_DEST parameter default value as /oradata/gqtzdb/archivelog
ALTER SYSTEM SET log_archive_dest_state_2=‘ENABLE‘ SCOPE=BOTH;
Mon Jul 03 18:19:10 2017
PING[ARC2]: Heartbeat failed to connect to standby ‘gqtzdb_dg‘. Error is 16047.
接着查看v$archive_dest视图，查看是否能找到原因，结果发现如下报错：
SQL> select dest_id,error from v$archive_dest;
DEST_ID ERROR
---------- -----------------------------------------------------------------
1
2 ORA-16047: DGID mismatch between destination setting and target
database
很明显，DGID不一样，去备库查看参数db_unique_name参数：
SQL> show parameter db_unique_name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_unique_name string gqtzdb
发现db_unique_name参数没有修改，仍然是主库的值，速度改过来，并重启备库：
SQL> alter system set db_unique_name=‘gqtzdb_dg‘ scope=both;
alter system set db_unique_name=‘gqtzdb_dg‘ scope=both
*
ERROR at line 1:
ORA-02095: specified initialization parameter cannot be modified
SQL> alter system set db_unique_name=‘gqtzdb_dg‘ scope=spfile;
System altered.
然后再在主库开启归档路径2，在备库运行命令，查看同步状态：
SQL> alter database recover managed standby database using current logfile disconnect from session;
Database altered.
SQL> select process,client_process,sequence#,status from v$managed_standby;
